100 mm Graduated Filters by Haida
Graduated ND filters in 100 x 150 mm for the Haida M10 and other 100 mm filter holders. Soft, hard or reverse graduation from ND 0.6 to ND 1.5 – individually or as a Red-Diamond kit.
Why use a graduated filter?
In landscape photography the sky is often much brighter than the foreground. A graduated ND filter darkens the upper part of the frame while leaving the lower part unchanged. This lets you expose sky and land correctly in a single shot – without bracketing or heavy editing.
Which graduation suits your subject?
- Soft edge: the darkening fades gently towards the centre. Ideal for mountains, hills and uneven horizons where a hard edge would show.
- Hard edge: a short, defined transition. Ideal for straight horizons such as the sea, lakes or flat landscapes.
- Reverse grad: strongest in the middle, lighter towards the top. For sunrises and sunsets when the brightest light sits right on the horizon.
Which strength do I need?
The ND value shows how much the filter darkens: ND 0.6 equals 2 stops, ND 0.9 3 stops, ND 1.2 4 stops and ND 1.5 5 stops. ND 0.9 is the most versatile choice to start with. For backlight and sunsets you'll usually want ND 1.2 or ND 1.5.
Single filter or Red-Diamond kit?
The kits contain several strengths of the same graduation type and cost less than buying the filters individually. Haida's Red-Diamond series is made of toughened optical glass, making it particularly shatter-resistant – handy when you swap filters quickly outdoors.
100 mm or 150 mm?
The 100 mm system fits most lenses with a filter thread and is more compact and lighter. For ultra-wide lenses with a bulbous front element and no filter thread, you'll usually need the larger 150 mm system. You'll find the right holder under filter holders.
